Here are some indicators to look out for:
– The journal has no address or contact information other than an email address listed.
– There are articles listed but no evidence of an editorial board to review those articles.
– The website has an overwhelming number of images from major publishers who would have no reason to partner with this journal.
– The editorial board seems to contain very prominent researchers who would be too busy to work with an unknown journal.
– There is no mention of an APF, which means you’ll likely receive an outrageous bill after your article has been rapidly accepted for publication.
-There is no mention of a peer review process or basic submission requirements.
